Electromagnetic Compatibility Supernetwork Modeling and Node Importance Evaluation

Study of super network has been conducted across many fields of science. Characteristics such as multilayer, multilevel and multicriteria make it an efficient method for modeling electromagnetic compatibility (EMC) problems. Owing to the increasing of electromagnetic signal density and electromagnetic interference (EMI), finding the key nodes in the EMC networks becomes significant to predesign and rectify of the electronic system. In this paper, we first modeling the EMC problems Based on the super network theory, then theoretically analyze the efficiency and degree contribution to evaluate the node importance. Full consideration is given to include both the global information and local information of network. Through this method, we can give primary importance to top-ranked nodes before the design of complex electronic system, so that EMC problems will be solved effectively. Finally, examples are illustrated to confirm that node importance can be distinguished effectively by this way.
